Supply Chain Design Model Based on Multi-supply Hubs

In order to explore the impact of upstream structural on supply chain design, Taking into consideration that the relationship between bill of material (BOM) and multi-hierarchical suppliers, based on the supply chain design with single supply hub model, this paper extended to establish supply chain design models with two supply hubs from the model with single Supply Hub. These mixed integer programming (MIP) models were computed by using combined genetic algorithm. The experiment found that the total cost and inventory level of supply chain design with two supply hubs were lower than those with single supply hub, and could restrain dasiaBullwhip effectpsila more efficiently than that without supply hub.
